Effect of Dipyridamole on the Survival of Experimental Critical Skin Flaps

Abstract
The effect of dipyridamole (Persantin) on the survival of experimental skin flaps was studied [in rats]. In controls 39% of the skin flap area survived. I.p. injection of dipyridamole 4 mg/kg twice daily starting 4 h preoperatively increased the surviving area by 18%. This increase is statistically significant (P < 0.05). The improved survival could be due to the vasodilatory action of the drug and/or proliferation of small blood vessels induced by the drug.
